Shadow Gray vs Upper West Side

Both from Benjamin Moore's palette. Shadow Gray reads as blue-grey, while Upper West Side reads as greige-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (40 vs 39), so they'll read as similarly Medium in most lighting conditions. Shadow Gray runs blue while Upper West Side is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 10.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
